Balanced Equations And Equilibrium Constants
... Given overall reaction (need to REVERSE first reaction, see Rule 2 for how this changes the equilibrium constant): N2O(g) + (1/2)O2(g) <---> 2NO(g) K = (1/K1)*(K2) = 8.5*10-13 2) When we reverse an equation we invert the value of K. Kreverse reaction = 1/(Kforward reaction) 3) When we multiply coeff ...

... The increasing monotony of the function S(U)|V implies the positiveness of 1/T=S/U|V. Furthermore, energy itself has to be also a monotonic increasing function of temperature at constant volume, U/T|V>0 because otherwise the system would be thermally unstable (energy would flow from colder to ho ...
